[0036] Specifically, two fixed clamps 7 are provided with positioning pins 9 on the outer surface, and the two positioning pins 9 are symmetrically distributed about the center line of the fixed clamp 7. The advantage is that after the cable joint is preliminarily fixed by the fixed clamp 7, the two positioning pins 9 are symmetrically inserted through the two fixed clamps 7 and are tightened to further enhance the clamping force of the fixed clamp 7 on the cable joint, prevent displacement or loosening of the cable joint in the protective clamp, effectively avoid the shaking and displacement of the cable joint in the protective clamp, and ensure that the cable joint is always in a stable fixed state even in the case of a large external force impact or vibration, thereby improving the protection ability of the protective clamp on the cable joint and reducing power failures such as poor contact and short circuit caused by loosening of the cable joint.

Then, the positioning pin 6 on the mounting bracket 5 is tightened, the fixed clamp 7 approaches the cable joint, the protective sleeve 8 in the fixed clamp 7 tightly fits the surface of the cable joint, and the clamping force is applied to the cable joint, completing the fixation of the cable joint. In the second embodiment, the plurality of positioning pins 6, fixed clamps 7 and protective sleeves 8 are equally spaced about the mounting bracket 5, which can more uniformly press the cable joint and further optimize the fixing effect. After the fixed clamp 7 is preliminarily fixed, the two symmetrically distributed positioning pins 9 are inserted through the two fixed clamps 7 and are tightened, further enhancing the clamping force of the fixed clamp 7 on the cable joint and preventing displacement or loosening thereof.
